I have given Green Ums to my labs for several years, and they do seem to help with yellow spots in the grass. However, I'm totally frustrated in trying to purchase them. I continually get email notices that they are "on sale," and when I go in (immediately) to purchase them, they are out of stock. So, I've switched over to another brand that I can actually purchase when I need it.

Works great!

I been giving this to my dog for 3 summers now. It works great to manage urine burn stains in the grass. My vet says it's a safe product. It's important not to give it to your dog year round and to take the recommended break from it. So I add it to his food from April to October to cover the months we have little or no snow on the ground. I still have burn areas to work on from the months he's not on it, but they are way less. I also recommend Scott's EZ Seed Dog Spot Repair to fix those spots. Just sprinkle it on and water it. Easy breezy!

It actually works and Zoey (my female Doberman) takes them like treats. No poking down the throat. Dead spots were covered in the lawn in less than 2 weeks and no more appeared.

I used this product in the past with an adult dog. The results were as advertised.Now, I have an 8 month old lab, and when I give him the prescribed dose, it gives him diarrhea.

Very Convenient

We used to give our dog the Green-Um treats. She loved them, but the bags were small and didn't hold very many treats. I had to order a bunch at a time to avoid ordering too often. That's why we switched to the tablets; one bottle takes up much less space and contains a large supply; the tablets are simply more convenient. I just drop one into our dog's bowl of dry food, and she gobbles it down with the rest of her meal. Very easy!
